PHP Класс Puli\Repository\Resource\Iterator\ResourceCollectionIterator
Use the iterator if you want to iterate a resource collection. You can
configure what the iterator should return as keys and values:
php
$iterator = new ResourceCollectionIterator(
$collection,
ResourceCollectionIterator::KEY_AS_PATH | ResourceCollectionIterator::CURRENT_AS_RESOURCE
);
foreach ($iterator as $path => $resource) {
...
}
If you want to iterate the collection recursively, wrap it in a
{@link RecursiveResourceIteratorIterator}:
php
$iterator = new RecursiveResourceIteratorIterator(
new ResourceCollectionIterator(
$collection,
ResourceCollectionIterator::KEY_AS_PATH | ResourceCollectionIterator::CURRENT_AS_RESOURCE
),
RecursiveResourceIteratorIterator::SELF_FIRST
);
foreach ($iterator as $path => $resource) {
...
}

Описание методов
__construct()
публичный Метод
The following constants can be used to configure the values returned by
the iterator:
* {@link CURRENT_AS_RESOURCE}: The {@link PuliResource} objects are
returned as values;
* {@link CURRENT_AS_PATH}: The resource paths are returned as values;
* {@link CURRENT_AS_NAME}: The resource names are returned as values.
The following constants can be used to configure the keys returned by
the iterator:
* {@link KEY_AS_CURSOR}: The collection keys are returned as keys;
* {@link KEY_AS_PATH}: The resource paths are returned as keys.
By default, the mode KEY_AS_PATH | CURRENT_AS_RESOURCE is used.
